slots/signals with QNetworkReply

[timmu]

I cannot figure out how to properly use slots/signals when QNetworkReply detects an error.
I'm trying to detect a website that doesn't exist and I'd like to see "host not found" error.
This is the main code:



QNetworkAccessManager* nam; QNetworkReply* reply;
nam = new QNetworkAccessManager(this);
QObject::connect(reply, SIGNAL(error(QNetworkReply::NetworkError)), this, SLOT(slotError(QNetworkReply::NetworkError)));

QUrl url; url.setUrl("http://www.random-wrong-website.com");
reply = nam->get(QNetworkRequest(url));


Here's my slot slotError()


void MyClass::slotError(QNetworkReply* reply)
{
//extract the error code from here
}


My questions:
1) Am I calling the slot correctly? I have a feeling I don't have the parameters right.
2) Do you know how to find out (in slotError()) what the error code was

Please help if you can. Thanks!!

Replace this line in slot definition.


void MyClass::slotError(QNetworkReply* reply)


With

void MyClass::slotError(QNetworkReply::NetworkError err)

thanks!

But what would be the slotError() prototype declaration in the h file? These don't work:



void slotError(class QNetworkReply);
or
void slotError(QNetworkReply::NetworkError err);

The slot signature should match the signal you want to connect it to ...
